Patented July 11, 1950 UNITED STATES PATENT ()FFICE 1 Claim.

This invention relates to new and useful improvements in high chairs andmore particularly to an adjustable high chair.

The primary feature of the present invention is to provide a high chairof the character referred to that is capable of being varied in height.

Another important feature of this invention is to provide a high chairthat permits the seat and back to be packed and shipped separately fromthe supporting stand.

A still further feature of this invention is to provide a device of thecharacter referred to that is neat and attractive in appearance, strongand durable in construction, relatively inexpensive to manufacture, andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure l is a perspective view of the high chair constructed inaccordance with the present invention.

Figure 2 is an enlarged fragmentary view in vertical section takenthrough the upright portions of the frame, the bar connecting saidportions and the tubular legs and showing the locking pins and thecompression springs therefor in elevation.

Referring now to the drawings in detail, wherein for the purpose ofillustration, I have disclosed a preferred embodiment of the presentinvention, the numeral 4 represents generally the supporting framehaving a pair of upright portions 5 and 6, said frame and uprightportions being constructed of a substantially hollow tubing the uprightportions 5, 6 being formed at the ends of a horizontal U-shaped base I.

Welded at 8 to the upper ends of said upright portions 5 and 6 are theouter ends of a connecting bar 9 substantially hollow throughout.

A pair of locking pins 10 and I I having one of their ends l2 hookedoutwardly are slidably carried within bar 9 and extend outwardly throughopenings l3 provided in the respective uprights 5 and B.

A washer I4 is suitably secured at l5 to each of said pins and adaptedto bear against one end of a coil spring [6 carried loosely on each ofsaid pins, the opposite end of said spring bearing against a circularstop ll secured within the bar 9.

The hooked ends l2 of said pins are adapted to be pulled inwardly towardeach other in a slot l8 provided in bar 9, whereby the outer ends ofpins I and H are pulled inwardly of the bar 9 and against thecompression of springs so that when the hooked ends of said pins arereleased the outer ends of said pins extend horizontally throughuprights 5 and 6.

The numeral ll represents a seat having a back rest l8, foot rest l9 anda pair of L-shaped arms 20 preferably circular in cross section, saidarms being secured at one end to the seat and the opposite end to theback rest.

A tray 2| having a pair of U-shaped brackets 22 is slidable on arms 20.

Extending downwardly from the forward corners of seat I! are a pair oftubular legs 23 and 24 having a plurality of vertically spaced openings25 therein. Said legs ar telescoped to fit into upright portions 5 and 6respectively and are held in vertical adjustment by the outer end ofpins in and II selectively engaging openings 25 in said legs as isclearly illustrated in Figure 2.

To remove seat I! from frame 4 the hook ends of pins I0 and l I arepulled toward each other and the seat is lifted upwardly so that legs 23and 24 disengage upright portions 5 and 6.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible of certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claim.

I claim:

In a chair, a seat, a single pair of legs for said seat at front cornersof the same, a U-shaped base frame adapted to rest flat on a supportingsurface and terminating in a pair of front tubular uprights with openupper ends in which said legs are vertically slidable, a tubularconnecting bar between said uprights provided with a longitudinal slottherein, and fastening means for holding said legs against slidingcomprising a pair of spring pressed pins in. said bar slidable intounfastening position and having curved hand grip ends extending out ofsaid slot for grasping to slide the pins.
